Let's divide 842165 by 80
The aim is to understand the frequency of 80 in 842165.

Let's proceed to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 80

Moving on to step 2:
80 goes into 84 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we take 80 away from 84, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 80

Step 3:
42 divided by 80 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 80

Step 4:
When dividing 421 by 80, we get 5 with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 105.0
If we subtract 400 from 421, we get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 80

Step 5:
80 can be fit into 216 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 1052.0
Subtract 160 from 216 to get 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 80

Advancing to step 6:
80 goes into 565 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 10527.0
Deduct 560 from 565 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 80, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10527.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 10527.06
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
80 goes into 200 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 10527.062
If we take 160 away from 200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10527.0625
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10527.0625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10527.0625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10527.0625 and a remainder of 0.0.
